UWP - How to exit an app

UWP - Exit an app

The following Universal Windows Platform application development tutorial demonstrates how we can exit from an app.

In this UWP tutorial, we will call the CoreApplication class Exit() method to exit the app. We also get the current application object and call its Exit() method to exit the app.

The CoreApplication class enables apps to handle state changes, manage windows, and integrate with a variety of UI frameworks. The CoreApplication class Exit() method shuts down the app.

The Application class encapsulates a Windows Presentation Foundation application. The Application implements the singleton pattern to provide shared access to its window, property, and resource scope services. Consequently, only one instance of the Application class can be created per AppDomain.

The Application class Current property gets the Application object for the current AppDomain. This property value is the Application object for the current AppDomain. Here we will call the Exit() method to exit the current application.
